Question

Express the following statement in the form of equations and solve: Twice a number decreased by 8 times the same number is equal to 18

Answer 1

Answer:

2N - 8N = 18

Number is - 3

Step-by-step explanation:

Twice a number decreased by 8 times the same number is equal to 18

Let say number = N

Twice a number  = 2N

8 times the same number  = 8N

Twice a number decreased by 8 times the same number is equal to 18

=> 2N - 8N = 18

on Solvind

=> -6N = 18

Dividing by -6 both sides

=> N = -3

Number is - 3

Answer 2

Answer:

Required Number is - 3

Step-by-step explanation:

In this question,

We have been given that Twice a number decreased by 8 times the same number is equal to 18

Therefore, according to the question,

Let the number be  X

Twice the number = 2X

8 times the same number  = 8X

Twice a number decreased by 8 times the same number is equal to 18

=> 2X - 8X = 18

on Solving we get,

=> -6X = 18

or, $X\ =\ -\frac{18}{6}$

or, X = -3

Therefore, required Number is - 3
